Epipolar

定义 Definition

epipolar(形容词)极线的;与极几何(epipolar geometry)有关的。常用于计算机视觉与摄影测量中,描述两幅图像之间由相机视角变化引起的几何约束(如极点、极线、极平面等)。

发音 Pronunciation (IPA)

/ppolr/

例句 Examples

The epipolar line tells us where the matching point may appear in the other image.
极线告诉我们,在另一张图像中匹配点可能出现的位置。

Using epipolar constraints, the algorithm narrows the search for correspondences and improves stereo depth estimation.
利用极线约束,该算法缩小了对应点搜索范围,并提升了双目深度估计的效果。

词源 Etymology

epipolar 来自 **epi-**(希腊语前缀,意为“在……之上/附加”)与 polar(与“极点/极”相关)。在计算机视觉中,它指围绕“极点(epipole)极线(epipolar line)”这一组概念形成的几何关系,因此用来描述与极几何相关的约束与结构。
